After gunslinger Ben Lattimore's (Harry Lauter) sister (Jodi Mitchell) is killed during a stagecoach robbery, he swears revenge on the two men responsible, in this 1965 Western. While pursuing them, he is bushwhacked and shot by the men's mother (Hanna Landy). After he recovers, Lattimore agrees to quit his vigilante crusade. But when he discovers that Marshal Jethro Karnin (Don "Red" Barry) has apprehended the pair and is transporting them by stagecoach to stand trial, he volunteers to ride along to help defend against the inevitable attempt to free the prisoners by members of their gang.
